This application claims the benefit of priority of U.S. Provisional No.61/873,755, filed Sep. 4, 2013, which is incorporated herein byreference in its entirety.

BACKGROUND OF THE INVENTION

Liver X receptor (LXR), first described by Willy, P. J., et al. (“LXR, anuclear receptor that defines a distinct retinoid response pathway,”Genes & Development 9:1033-1045 (Cold Spring Harbor Laboratory Press)),is a member of the nuclear hormone superfamily and consists of twosubtypes, LXR alpha and LXR beta. LXR modulates a variety ofphysiological responses including inflammation in various tissues andcell types, regulation of cholesterol absorption, cholesterolelimination (bile acid synthesis), and transport of cholesterol fromperipheral tissues via plasma lipoproteins to the liver. LXR alsoregulates genes involved in glucose metabolism, cholesterol metabolismin the brain and apolipoproteins such as ApoE and its isoforms, that areimplicated in cellular differentiation and apopotosis, inflammation,neurodgenerative disease, and infectious diseases (Geyeregger, R. etal., Cell. Mol. Life Sci. 2006, 63:524-539). LXR also regulates genes,including ApoE, in melanoma cells and melanocytes (Lim, K. M., et al., JInvest Dermatol. (2013) 133(4):1063-71) and thus is also a therapeutictarget for treatment of certain types of cancers.

DETAILED DESCRIPTION OF THE INVENTION Metastatic Melanoma

Expression levels of certain micro RNAs (miRNAs), including miRNA-1908,miRNA-199a-5p and miRNA-199a-3p and ApoE, including ApoE3 and ApoE4,correlate with the progession of malignant melanomas and metastaticdisease as well as frequencies in other cancers (Tavazoie, S. F., etal., Cell (2012) 151:1-15). The discovery that the three miRNAscombinatorially target metastatic melanoma suppression establishes theirpotential as melanoma biomarkers. In particular, melanoma cell-secretedApoE suppresses metastaic invasion and endothelial recruitment.Cancer-derived ApoE has been directly linked to modulation of metastaticangiogenesis in melanoma cells as well as in other cancer types. Agentsthat increase the expression of ApoE are therefore potential therapeuticagents for suppressing endothelial migration and tumor invasion and forthe treatment of malignant metastatic melanoma and other cancers. LXRagonists have been shown to regulate ApoE in primary human melanomacells (Lim, K. M., et al., J Invest Dermatol. (2013) 133(4):1063-71),identifying ApoE as a LXR target gene in melanoma cells and inmelanocytes. As ApoE up-regulation is associated with tumor suppressionin melanoma cells, LXR agonists should be effective in therapeuticintervention and prevention of metastatic melanoma and other cancersassociated with ApoE-related angiogenesis. In some embodiments describedherein are methods to treat cancer patients using LXR agonists who haveabnormal levels of apolipoprotein E (ApoE), including lower expressionlevels of ApoE and its isoforms using a compound of Formula I, IA, IB,IC, II, IIA, or IIB. In some embodiments described herein are methods totreat metastatic melanoma using a compound of Formula I, IA, IB, IC, II,IIA, or IB.

Alzheimer's Disease, Neurodegenerative Disorders, Traumatic Brain Injury

LXRs are key regulators of genes that inhibit the inflammatory responsein multiple cell types, including microglial cells in the CNS. LXR hasbeen implicated in playing a critical role in the removal of accumulatedamyloid beta in the brain. In particular, LXR agonists increase theexpression of the ATP-binding cassette transporter ABCA1 (a cholesteroltransporter), to facilitate the lipidation of ApoE and directly promotemicroglia-mediated clearance of Aβ.

Data from in vitro and in vivo studies (Pfrieger, F. W. et al., Science(2001); 294:1354-7; Lazo, J. S. et al., J Biol Chem. (2005) 280:4079-88)validate the role of ApoE in facilitating the proteolytic clearance ofsoluble Aβ from the brain. The capacity of ApoE to promote Aβdegradation is isoform specific and dependent upon lipidation status.ApoE is lipidated by ABCA1 in multiple cell types, transferring bothphospholipids and cholesterol to ApoA-I in the periphery, and bothApoA-I and ApoE in brain. In this manner, lipidated ApoE as well asApoA-I transport cholesterol and other lipids from astrocytes. Thisprocess is necessary to maintain synaptic plasticity and neuronalremodeling in a healthy brain.

Three independent studies have reported that global deletion of ABCA1 inAPP transgenic mice results in increased levels of amyloid depositionwithout a significant effect on Aβ generation. Studies with the LXRagonists in APP-expressing mice show LXR agonism decreases Aβ levels,and this decrease is correlated with increased ApoA-I and ApoE levels inthe brains of treated animals (Koldamova R. et al., Mol Neurodegener(2007); 2:20). Using the same LXR agonist in a Tg2576 mouse model ofAlzheimer's disease, researchers have shown a pronounced improvement incognitive performance (Jacobsen J. S., et al., Mol Cell Neurosci. (2007)34:621-8).

The outcomes of these studies strongly suggest that ABCA1 and LXRregulate ApoE and ApoA-I lipidation, which in turn impacts Aβaggregation and allows for Aβ clearance and that LXR agonists should beeffective in treating neurodegenerative disorders such as Alzheimer'sdisease. In some embodiments described herein are methods to treatAlzheimer's disease using a compound of Formula I, IA, IB, IC, II, IIA,or IIB.

Parkinson's Disease

LXRs have been shown to play an important role in the CNS both inreducing inflammation in microglia and astrocytes and in effecting Abetaclearance with potential implications in the treatment of Parkinson'sdisease. Recent data show that LXR plays a role in the formation ofsuperficial cortical layers and migration of later-born neurons inembryonic mice. LXR agonists have a positive therapeutic effect ondopaminergic neurons in the substantia nigra in a MPTP-induced rodentmodel of Parkinson's disease where the MPTP-induced loss of dopaminergicneurons was significantly reduced in the mice treated with the LXRagonist relative to vehicle-treated animals (Gustafsson, J. A.; Proc.Natl. Acad. Sci. U.S.A. (2012) 109:13112-13117). LXR agonist treatmentalso resulted in an attenuation of the increase in GFAP-positive cellsin the substantia nigra pars compacta. Based on the above studies andother data in the literature, it is likely that LXR plays a key role inthe pathology of Parkinson's disease. Thus, selective LXR agonists withrequisite brain distribution should offer a novel therapeutic forParkinson's disease. In some embodiments described herein are methods totreat Parkinson's disease using a compound of Formula I, IA, IB, IC, II,IIA, or IIB.

Age-Related Macular Degeneration (AMD) Wet and Dry Forms

LXR pathways that have been studied in the CNS, such as regulation ofABC transporters and apolipoproteins such as ApoE and isoforms, are alsopertinent in the retinal cells and implicated in the pathology of AMD,both wet and dry. In retinal pigment epithelium cells, both primary andimmortalized, LXR agonists and modulators induce the expression of ABCA1and ApoE, target genes implicated in the pathology of AMD (Ishida,Journal ofLipid Research (2004) 45: 267-271). In mouse models of AMD,non-selective LXR agonists have been shown to provide beneficial effectson AMD progression (Sene, Cell Metabolism, 2013, 17: 549-561). Thus,selective LXR agonists and modulators should have a therapeutic benefitin the treatment of both wet and dry forms of AMD, a diseasecharacterized by abnormal cholesterol signaling and inflammatoryconditions.

Use of Protecting Groups

In the reactions described, it may be necessary to protect reactivefunctional groups, for example hydroxy, amino, imino, thio or carboxygroups, where these are desired in the final product, in order to avoidtheir unwanted participation in reactions. Protecting groups are used toblock some or all of the reactive moieties and prevent such groups fromparticipating in chemical reactions until the protective group isremoved. It is preferred that each protective group be removable by adifferent means. Protective groups that are cleaved under totallydisparate reaction conditions fulfill the requirement of differentialremoval.

Protective groups can be removed by acid, base, reducing conditions(such as, for example, hydrogenolysis), and/or oxidative conditions.Groups such as trityl, dimethoxytrityl, acetal and t-butyldimethylsilylare acid labile and may be used to protect carboxy and hydroxy reactivemoieties in the presence of amino groups protected with Cbz groups,which are removable by hydrogenolysis, and Fmoc groups, which are baselabile. Carboxylic acid and hydroxy reactive moieties may be blockedwith base labile groups such as, but not limited to, methyl, ethyl, andacetyl in the presence of amines blocked with acid labile groups such ast-butyl carbamate or with carbamates that are both acid and base stablebut hydrolytically removable.

Carboxylic acid and hydroxy reactive moieties may also be blocked withhydrolytically removable protective groups such as the benzyl group,while amine groups capable of hydrogen bonding with acids may be blockedwith base labile groups such as Fmoc. Carboxylic acid reactive moietiesmay be protected by conversion to simple ester compounds as exemplifiedherein, which include conversion to alkyl esters, or they may be blockedwith oxidatively-removable protective groups such as2,4-dimethoxybenzyl, while co-existing amino groups may be blocked withfluoride labile silyl carbamates.

Allyl blocking groups are useful in then presence of acid- andbase-protecting groups since the former are stable and can besubsequently removed by metal or pi-acid catalysts. For example, anallyl-blocked carboxylic acid can be deprotected with a Pd⁰-catalyzedreaction in the presence of acid labile t-butyl carbamate or base-labileacetate amine protecting groups. Yet another form of protecting group isa resin to which a compound or intermediate may be attached. As long asthe residue is attached to the resin, that functional group is blockedand cannot react. Once released from the resin, the functional group isavailable to react.

Typically blocking/protecting groups may be selected from:

Other protecting groups, plus a detailed description of techniquesapplicable to the creation of protecting groups and their removal aredescribed in Greene and Wuts, Protective Groups in Organic Synthesis,3rd Ed., John Wiley & Sons, New York, N.Y., 1999, and Kocienski,Protective Groups, Thieme Verlag, New York, N.Y., 1994, which areincorporated herein by reference for such disclosure).

Methods of Treatment and Prevention

In one embodiment, provided herein are methods for stimulation of LXRactivity in a cell by contacting the cell with an LXR modulator.Examples of such LXR modulators are described above. Other LXRmodulators that can be used to stimulate the LXR activity are identifiedusing screening assays that select for such compounds, as described indetail herein.

In another aspect, provided herein are methods of modulating LXRactivity for the treatment of diseases, disorders or conditionsdescribed herein. Accordingly, in an exemplary embodiment, providedherein are methods which involve contacting a cell with an LXR modulatorthat induces TIMP1, ASAH1, SPTLC1, SMPD1, LASS2, TXNRD1, GPX3, GSR, CAT,ApoE, ABCA1, ABCA2, ABCA12, ABCA13, ABCG1, aSyn, and/or decorinexpression and/or inhibits TNFα, MMP1, MMP3, and/or IL-8 expression.These methods are performed in vitro (e.g., by culturing the cell withan LXR modulator) or, alternatively, in vivo (e.g., by administering anLXR modulator to a subject). As such, the present methods are directedto treating a subject that would benefit from induction of TIMP1, ASAH1,SPTLC1, SMPD1, LASS2, TXNRD1, GPX3, GSR, CAT, ApoE, ABCA1, ABCA2,ABCA12, ABCA13, ABCG1, aSyn, and/or decorin expression and/or inhibitionof TNFα, MMP1, MMP3, and/or IL-8 expression.

LXR modulators increase expression of genes involved in fatty acidsynthesis and lipid transport. The LXR ligand induced the expression ofgenes involved in fatty acid synthesis, namely SREBF1, SREBF2, FASN, andSCD, and genes involved in cholesterol and phospholipid transport namelyAPOE, APOD, ABCG1, ABCA1, ABCA12, ABCA2, and ABCA13. LXR modulatorsincrease the expression of LASS4 and SMPD2.

Pharmaceutical Compositions and Methods of Administration of LXRModulators

Administration of LXR modulators as described herein can be in anypharmacological form including a therapeutically effective amount of anLXR modulator alone or in combination with a pharmaceutically acceptablecarrier. The term “subject” is intended to include living organisms inwhich an immune response can be elicited, for example, mammals.

Pharmaceutical compositions may be formulated in a conventional mannerusing one or more physiologically acceptable carriers includingexcipients and auxiliaries which facilitate processing of the activecompounds into preparations which can be used pharmaceutically. Properformulation is dependent upon the route of administration chosen.Additional details about suitable excipients for pharmaceuticalcompositions described herein may be found, for example, in Remington:The Science and Practice of Pharmacy, Nineteenth Ed (Easton, Pa.: MackPublishing Company, 1995); Hoover, John E., Remington's PharmaceuticalSciences, Mack Publishing Co., Easton, Pa. 1975; Liberman, H. A. andLachman, L., Eds., Pharmaceutical Dosage Forms, Marcel Decker, New York,N.Y., 1980; and Pharmaceutical Dosage Forms and Drug Delivery Systems,Seventh Ed. (Lippincott Williams & Wilkins 1999), herein incorporated byreference for such disclosure.

A pharmaceutical composition, as used herein, refers to a mixture of acompound of Formula I, IA or II described herein, with other chemicalcomponents, such as carriers, stabilizers, diluents, dispersing agents,suspending agents, thickening agents, and/or excipients. Thepharmaceutical composition facilitates administration of the compound toan organism. In practicing the methods of treatment or use providedherein, therapeutically effective amounts of compounds described hereinare administered in a pharmaceutical composition to a mammal having adisease, disorder, or condition to be treated. In some embodiments, themammal is a human. A therapeutically effective amount can vary widelydepending on the severity of the disease, the age and relative health ofthe subject, the potency of the compound used and other factors. Thecompounds of Formula I, IA or II can be used singly or in combinationwith one or more therapeutic agents as components of mixtures (as incombination therapy).

The pharmaceutical formulations described herein can be administered toa subject by multiple administration routes, including but not limitedto, oral, parenteral (e.g., intravenous, subcutaneous, intramuscular),intranasal, buccal, topical, rectal, or transdermal administrationroutes. Moreover, the pharmaceutical compositions described herein,which include a compound of Formula I, IA or II described herein, can beformulated into any suitable dosage form, including but not limited to,aqueous oral dispersions, liquids, gels, syrups, elixirs, slurries,suspensions, aerosols, controlled release formulations, fast meltformulations, effervescent formulations, lyophilized formulations,tablets, powders, pills, dragees, capsules, delayed releaseformulations, extended release formulations, pulsatile releaseformulations, multiparticulate formulations, and mixed immediate releaseand controlled release formulations.

For treatment of solid tumors, localized delivery is also an option.Such delivery may be by injection, or may be topical, transmucosal, andthe like. If the drugs are directed to treatment of melanoma, topicaladministration is a viable option.

For systemic parenteral delivery, a variety of physiologicallyacceptable carriers is available, including nanoparticulateformulations, liposomes, micelles, and the like. Such carriers can alsobe targeted using antibodies or fragments thereof specific for thetargets, or by using receptor ligands. “Antibodies” includes all forms,including human and humanized antibodies as well as recombinantlyproduced single-chain antibodies and fragments.

Formulations for systemic administration by parenteral routes mayinclude aqueous as well as lipophilic carriers. Similarly, formulationsfor administration, for example, by inhalation will include carriersthat promote absorption across the nasal barrier and may be administeredby aerosol spray using propellants such as trichlorofluoromethane,carbon dioxide or other propellant. The formulation to be administeredmay also be in the form of a powder or slurry.

The pharmaceutical compositions described herein, which include acompound of Formula I, IA or II described herein, may be administeredusing sustained release formulations including implants. Such implantsmay be used proximal to any solid tumor or implanted within said tumor.

Pharmaceutical compositions including a compound described herein may bemanufactured in a conventional manner, such as, by way of example only,by means of conventional mixing, dissolving, granulating, dragee-making,levigating, emulsifying, encapsulating, entrapping or compressionprocesses.

Dose administration can be repeated depending upon the pharmacokineticparameters of the dosage formulation and the route of administrationused.

It is especially advantageous to formulate compositions in dosage unitform for ease of administration and uniformity of dosage. Dosage unitform as used herein refers to physically discrete units suited asunitary dosages for the mammalian subjects to be treated; each unitcontaining a predetermined quantity of active compound calculated toproduce the desired therapeutic effect in association with the requiredpharmaceutical carrier. The specification for the dosage unit forms aredictated by and directly dependent on (a) the unique characteristics ofthe LXR modulator and the particular therapeutic effect to be achievedand (b) the limitations inherent in the art of compounding such anactive compound for the treatment of sensitivity in individuals. Thespecific dose can be readily calculated by one of ordinary skill in theart, e.g., according to the approximate body weight or body surface areaof the patient or the volume of body space to be occupied. The dose willalso be calculated dependent upon the particular route of administrationselected. Further refinement of the calculations necessary to determinethe appropriate dosage for treatment is routinely made by those ofordinary skill in the art. Such calculations can be made without undueexperimentation by one skilled in the art in light of the LXR modulatoractivities disclosed herein in assay preparations of target cells. Exactdosages are determined in conjunction with standard dose-responsestudies. It will be understood that the amount of the compositionactually administered will be determined by a practitioner, in the lightof the relevant circumstances including the condition or conditions tobe treated, the choice of composition to be administered, the age,weight, and response of the individual patient, the severity of thepatient's symptoms, and the chosen route of administration.

Toxicity and therapeutic efficacy of such LXR modulators can bedetermined by standard pharmaceutical procedures in cell cultures orexperimental animals, for example, for determining the LD₅₀ (the doselethal to 50% of the population) and the ED₅₀ (the dose therapeuticallyeffective in 50% of the population). The dose ratio between toxic andtherapeutic effects is the therapeutic index and it can be expressed asthe ratio LD₅₀/ED₅₀. LXR modulators that exhibit large therapeuticindices are preferred. While LXR modulators that exhibit toxic sideeffects may be used, care should be taken to design a delivery systemthat targets such modulators to the site of affected tissue in order tominimize potential damage to uninfected cells and, thereby, reduce sideeffects.

The data obtained from the cell culture assays and animal studies can beused in formulating a range of dosage for use in humans. The dosage ofsuch LXR modulators lies preferably within a range of circulatingconcentrations that include the ED₅₀ with little or no toxicity. Thedosage may vary within this range depending upon the dosage formemployed and the route of administration utilized. For any LXR modulatorused in a method described herein, the therapeutically effective dosecan be estimated initially from cell culture assays. A dose may beformulated in animal models to achieve a circulating plasmaconcentration range that includes the IC₅₀ (i.e., the concentration ofLXR modulator that achieves a half-maximal inhibition of symptoms) asdetermined in cell culture. Such information can be used to moreaccurately determine useful doses in humans. Levels in plasma may bemeasured, for example, by high performance liquid chromatography.

Monitoring the influence of LXR modulators on the induction of TIMP1,ASAH1, SPTLC1, SMPD1, LASS2, TXNRD1, GPX3, GSR, CAT, ApoE, ABCA1, ABCA2,ABCA12, ABCA13, ABCG1, αSyn, and/or decorin expression and/or inhibitionof TNFα, MMP1, MMP3, and/or IL-8 expression is applied in clinicaltrials. For example, the effectiveness of an LXR modulator is monitoredin clinical trials of subjects exhibiting increased TIMP1, ASAH1,SPTLC1, SMPD1, LASS2, TXNRD1, GPX3, GSR, CAT, ApoE, ABCA1, ABCA2,ABCA12, ABCA13, ABCG1, αSyn, and/or decorin expression and/or decreasedTNFα, MMP1, MMP3, and/or IL-8 expression. In such clinical trials, theexpression of TIMP1, ASAH1, SPTLC1, SMPD1, LASS2, TXNRD1, GPX3, GSR,CAT, ApoE, ABCA1, ABCA2, ABCA12, ABCA13, ABCG1, cSyn, decorin, TNFα,MMP1, MMP3, and/or IL-8 is used as a “read out” or marker.

Thus, to study the effect of LXR modulators, for example, in a clinicaltrial, cells are isolated and RNA prepared and analyzed for the levelsof expression of TIMP1, ASAH1, SPTLC1, SMPD1, LASS2, TXNRD1, GPX3, GSR,CAT, ApoE, ABCA1, ABCA2, ABCA12, ABCA13, ABCG1, αSyn, decorin, TNFα,MMP1, MMP3, and/or IL-8. The levels of gene expression (i.e., a geneexpression pattern) is quantified, for example, by Northern blotanalysis or RT-PCR, by measuring the amount of protein produced, or bymeasuring the levels of activity of TIMP1, ASAH1, SPTLC1, SMPD1, LASS2,TXNRD1, GPX3, GSR, CAT, ApoE, ABCA1, ABCA2, ABCA12, ABCA13, ABCG1, cSyn,decorin, TNFα, MMP1, MMP3, and/or IL-8, all by methods well known tothose of ordinary skill in the art. In this way, the gene expressionpattern serves as a marker, indicative of the physiological response ofthe cells to the LXR modulator. Accordingly, this response state isdetermined before, and at various points during, treatment of theindividual with the LXR modulator.

Also provided is a method for monitoring the effectiveness of treatmentof a subject with an LXR modulator comprising the steps of (i) obtaininga pre-administration sample from a subject prior to administration ofthe LXR modulator; (ii) detecting the level of expression of TIMP1,ASAH1, SPTLC1, SMPD1, LASS2, TXNRD1, GPX3, GSR, CAT, ApoE, ABCA1, ABCA2,ABCA12, ABCA13, ABCG1, cSyn, decorin, TNFα, MMP1, MMP3, and/or IL-8;(iii) obtaining one or more post-administration samples from thesubject; (iv) detecting the level of expression of TIMP1, ASAH1, SPTLC1,SMPD1, LASS2, TXNRD1, GPX3, GSR, CAT, ApoE, ABCA1, ABCA2, ABCA12,ABCA13, ABCG1, αSyn, decorin, TNFα, MMP1, MMP3, and/or IL-8 in thepost-administration samples; (v) comparing the level of expression ofTIMP1, ASAH1, SPTLC1, SMPD1, LASS2, TXNRD1, GPX3, GSR, CAT, ApoE, ABCA1,ABCA2, ABCA12, ABCA13, ABCG1, αSyn, decorin, TNFα, MMP1, MMP3, and/orIL-8 in the pre-administration sample with the TIMP1, ABCA12, decorin,TNFα, MMP1, MMP3, and/or IL-8 expression in the post administrationsample or samples; and (vi) altering the administration of the LXRmodulator to the subject accordingly.

For example, increased administration of the LXR modulator may bedesirable to increase TIMP1, ASAH1, SPTLC1, SMPD1, LASS2, TXNRD1, GPX3,GSR, CAT, ApoE, ABCA1, ABCA2, ABCA12, ABCA13, ABCG1, cSyn, and/ordecorin expression to higher levels than detected and/or reduce TNFα,MMP1, MMP3, and/or IL-8 expression to lower levels than detected, thatis, to increase the effectiveness of the LXR modulator. Alternatively,decreased administration of the LXR modulator may be desirable todecrease TIMP1, ASAH1, SPTLC1, SMPD1, LASS2, TXNRD1, GPX3, GSR, CAT,ApoE, ABCA1, ABCA2, ABCA12, ABCA13, ABCG1, αSyn, and/or decorinexpression to lower levels than detected or activity and/or to increaseTNFα, MMP1, MMP3, and/or IL-8 expression to higher levels than detected,that is, to decrease the effectiveness of the LXR modulator. Accordingto such an embodiment, TIMP1, ASAH1, SPTLC1, SMPD1, LASS2, TXNRD1, GPX3,GSR, CAT, ApoE, ABCA1, ABCA2, ABCA12, ABCA13, ABCG1, cSyn, decorin,TNFα, MMP1, MMP3, and/or IL-8 expression may be used as an indicator ofthe effectiveness of an LXR modulator, even in the absence of anobservable phenotypic response.

Screening Assays

In one embodiment, expression levels of cytokines and metalloproteasesdescribed herein are used to facilitate design and/or identification ofcompounds that work through an LXR-based mechanism. Accordingly providedherein are methods (also referred to herein as “screening assays”) foridentifying modulators, i.e., LXR modulators, that have a stimulatory orinhibitory effect on, for example, TIMP1, ASAH1, SPTLC1, SMPD1, LASS2,TXNRD1, GPX3, GSR, CAT, ApoE, ABCA1, ABCA2, ABCA12, ABCA13, ABCG1, αSyn,decorin, TNFα, MMP1, MMP3, and/or IL-8 expression.

An exemplary screening assay is a cell-based assay in which a cell thatexpresses LXR is contacted with a test compound, and the ability of thetest compound to modulate TIMP1, ASAH1, SPTLC1, SMPD1, LASS2, TXNRD1,GPX3, GSR, CAT, ApoE, ABCA1, ABCA2, ABCA12, ABCA13, ABCG1, αSyn,decorin, TNFα, MMP1, MMP3, and/or IL-8 expression through an LXR-basedmechanism. Determining the ability of the test compound to modulateTIMP1, ASAH1, SPTLC1, SMPD1, LASS2, TXNRD1, GPX3, GSR, CAT, ApoE, ABCA1,ABCA2, ABCA12, ABCA13, ABCG1, cSyn, decorin, TNFα, MMP1, MMP3, and/orIL-8 expression is accomplished by monitoring, for example, DNA, mRNA,or protein levels, or by measuring the levels of activity of TIMP1,ASAH1, SPTLC1, SMPD1, LASS2, TXNRD1, GPX3, GSR, CAT, ApoE, ABCA1, ABCA2,ABCA12, ABCA13, ABCG1, αSyn, decorin, TNFα, MMP1, MMP3, and/or IL-8. Thecell, for example, is of mammalian origin, e.g., human. Novel modulatorsidentified by the above-described screening assays are used fortreatments as described herein.

Example 12: Induction of Expression of LXR Receptors

Clonetics® Normal Human Epidermal Keratinocytes (NHEKs) are obtainedfrom Cambrex Bio Science, Inc. The proliferating T-25 (C2503TA25)pooled, neonatal keratinocytes are expanded in Clonetics® KGM-2serum-free medium (CC-3107) and subcultured as needed using therecommended Clonetics® ReagentPack™ (CC-5034). Due to a light-sensitivecomponent in the medium, all manipulations are done in low light.

For experiments, 1.6 million NHEK cells are plated in growth medium on100 mm dishes and allowed to grow to ˜75% confluence. On the day oftreatment, the dishes are rinsed once with KGM-2 minus hydrocortisone;then, vehicle (0.1% DMSO) or 1 jaM or an LXR agonist described herein,is added for 6 h in hydrocortisone-deficient KGM-2. After 6 h, thetreatment medium is temporarily removed, the dishes washed withDulbecco's Phosphate Buffered Saline, and then half of the treatmentsare exposed to 8 J/m² ultraviolet light using a Stratagene UVStratalinker® 2400. Treatments are replaced and 18 h later the samplesare harvested for RNA processing using TRIzol®D Reagent (Invitrogen).

RNA is extracted as described above. UV irradiation of NHEKs slightlyreduced the expression of LXRα. Treatment of keratinocytes with the LXRmodulator (1 jaM) induces the expression of LXRα in both UV-unexposedand UV-exposed keratinocytes. UV treatment of NHEKs down-regulates LXRPexpression, and this UV-mediated inhibition of LXRP expression isreversed by treatment with the LXR modulator. Therefore, induction ofexpression of both LXR receptors in UV-exposed keratinocytes by an LXRmodulator indicates efficacy of the LXT modulator. Further, LXRmodulators may help the UV-exposed keratinocytes/skin to be moreresponsive to its effects.

Gal4 LXRβ Cotransfection Assay

For transient transfection of HEK 293 cells, 6×10³ cells are plated into96-well dishes. Each well is transfected with 25 ng 5×UAS-luciferasereporter (pG5luc) and 25 ng of pM human LXRβ (AA 153-461) LBD plasmidusing Fugene 6 reagent (Roche; Indianapolis, Ind.). The chimeric proteinis assessed for the ability to transactivate a Gal4-responsiveluciferase reporter plasmid in a concentration-responsive manner tocompounds (0.01-10 μM). Luciferase activity at each dose concentrationis measured in triplicate using standard substrate reagents (BDBiosciences; San Diego, Calif.). Data is expressed as relative lightunits and are shown in Table 1.
